WINDOW.

sPFcIFreArIoNrormin part of Iletters Patent No. 727,882, dated M... 12, 1903. Application filed October 1, 1902. Serial No. 125,454. (Ndmodel-l To all whom it neoty concern:

Be it known that I, CHARLES BIOKEL, a

' citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented and produced a new and original Improvement in Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object ofthis invention is to facilitate the removal of window-sashes from their frames.

It consists in the improved window and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embracedin the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several fig; ures, Figure 1 is an inside elevation of the improved window. Figs. 2 and 3 are sectional views of the same taken on lines a; and 11 respectively. Fig. 4 is a perspective view of a portion of the same.

section taken on line .2 of Fig. 5. Fig. 7 is a broken perspective View illustrating the constructions of a certain slide, and Figs. 8 and 9 show the same in connection with awindowsash.

In said drawings, a indicates the windowframe, having side stiles b b of peculiar construction, and c and cl represent the upper and lower sashes, respectively. Said stiles b b are right-angular triangles in crosssection in general shape, the outer sides e e of the frame being the bases of the angles,

the inner sides or edges ff lying opposite the bases and toward the interior of the house, and the longest sides of the triangles serving as the side walls g of the'window-opening.

Said side walls g g are grooved vertically to,

receive slides 71, the grooves being preferably undercut to receive dovetails of the slides. The dovetail slides are preferably inserted in the grooves of the stiles prior to the final joinfrom the slides.

;to removal of stop-beads, &c., Fig. 5 is a detail section, takenon line z of Fig. 6, and Fig. 6 is a detail ing of the assembled parts of the frame, as will be understood. Said slides are preferably tongued or grooved to engage the correspond 'ingly tongned or grooved sashes and'are of a length somewhat shorter than the sashes, so that the latter may be readily disconnected from the said slides when it is found desirable to remove the sashes from the window-frame for the purpose of cleaning or repair.,. The oppositely-inclined side walls of the frame 'form a flaring opening, larger toward the room, andthus the sashes may be conveniently removed from the frame when withdrawn 7 Said slides hare provided with handled spring-catches m, which at one end are fastened, as at 70, to the outside of the slide and at the opposite free end are provided with lugs Z, adapted to enter through the slides h intoa socket in the sash to lock the said sash and the slides together, so that they will work together when the sash is raised or lowered.

By simply drawing the catch m away from the sash the latter may be pushed away from the slide or the slide away from the sash, and the latter will then be free to be drawn inward away from the frame, as will be understood, and thus the trouble and damage due is avoided.

What I claim as new is 1. The combination with the window-frame having stiles with inclined and grooved side walls, of slides permanently arranged in the grooves of the stiles and having tongues to enter grooves in the'sashes, sashes having and sashes together when sliding-in the win- 'dow frame and, when detached from the sashes adapted, to permit the said sashesto slide away from connection with said slides to permit a clear removal of the sash from the window-frame, substantially as set forth.

2. The combination with the window-frame having undercut grooves in the stiles thereof, of dovetailed slides arranged and adapted to slide vertically in said grooves, a window-sash adapted to slide on said slides out of and into operative relation one with the other, and a catch for holding said sash and slides in operative relation, said catch permitting a detachment of parts whereby the sash may be removed from the slides, substantially as set forth.

3. The combination with the Window-frame having undercut grooves in the stiles thereof, of dovetailed slides arranged in said undercut grooves, a Window-sash grooved to receive said slides and socketed to receive catches, and handled spring-catches fastened to the 10 slides and having lugs adapted to enter into the sockets of the sashes, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 24th day of September, 1902.

CHARLES BIOKEL.
